Boundary-to-Solution Mapping for Groundwater Flows in a Toth Basin [PDF]
, 2023 In this paper, the authors propose a new approach to solving the groundwater flow equation in the Toth basin of arbitrary top and bottom topographies using deep learning. Instead of using traditional numerical solvers, they use a DeepONet to produce the boundary-to-solution mapping.

Interaction between seepage and temperature fields in different groundwater flow systems
地质科技通报, 2022 In the regions with rich geothermal resources, it is necessary to study the interaction between the seepage and temperature fields under different groundwater flow systems.Based on numerical simulation and sandbox experiments in a two-dimensional ...

Sensitivity Analysis of Groundwater Flow [PDF]
Hydrology Research, 1991 A numerical model developed for sensitivity analysis of groundwater flow is presented. Sensitivity analysis is a useful complementary aid for groundwater flow modelling to assess the importance of various governing flow parameters to the behaviour of any specific flow problem.

Entropy, 2014 The groundwater flow system is typical dissipative structure system, and its evolution can be described with system information entropies. The information entropies of groundwater in Shijiazhuang City had been calculated between 1960 and 2005, and the ...

Investigating riparian groundwater flow close to a losing river using diurnal temperature oscillations at high vertical resolution [PDF]
Hydrology and Earth System Sciences, 2012 River-water infiltration is of high relevance for hyporheic and riparian groundwater ecology as well as for drinking water supply by river-bank filtration. Heat has become a popular natural tracer to estimate exchange rates between rivers and groundwater.

Lagrangian complexity persists with multimodal flow forcing in poroelastic systems [PDF]
, 2020 We extend previous analyses of the origins of complex transport dynamics in poroelastic media to the case where the input transient signal at a boundary is generated by a multimodal spectrum. By adding harmonic and anharmonic modal frequencies as perturbations to a fundamental mode we examine how such multimodal signals affect the Lagrangian complexity

SIMULASI NUMERIK PADA ALIRAN AIR TANAH MENGGUNAKAN COLLOCATION FINITE ELEMENT METHOD
E-Jurnal Matematika, 2018 This research presents a numerical simulation on groundwater flow using collocation finite element method (CFEM). Groundwater flow is known as the flow of water beneath the soil. Generally, groundwater flow is generated due to high hydraulic differences.

Natural Groundwater Systems Can Display Chaotic Mixing at the Darcy Scale [PDF]
Water Resources Research, 55, 3347--3374 (2019), 2018 Although steady, isotropic Darcy flows are inherently laminar and non-mixing, it is well understood that transient forcing via engineered pumping schemes can induce rapid, chaotic mixing in groundwater. In this study we explore the propensity for such mixing to arise in natural groundwater systems subject to cyclical forcings, e.g.
